A/N: So sorry I haven't posted IN AGES, but with school and all I have barely found the time to write. However, I felt inspired this weekend and came up with something I've been wanting to do for ages. So here it goes. I hope you enjoy and review!

Cecily and Gabriel's First 'Date' (TID)

Cecily glanced at her sweaty hand laced in Gabriel's as they made their way towards the Big Ben Tower, both dressed in gear – apparently demons were very fond of the old golden coloured monument.

When the Lightwood had asked her if she wanted to go out with him (after he was sure Will Herondale's ears were far enough to not hear the private invitation) this had not been what the blue eyed girl had in mind. However it wasn't all that bad. After all, Gabriel had took her hand in his as soon as they stepped out of the Institute; and despite her surprise over the protective gesture, Cecy couldn't have felt happier as she noticed that her hand seemed to have been made to fit his.

The Lightwood boy, on the other hand, wondered if it had been a good idea to bring her out of the Institute and into the danger, knowing that she was such an experienced Shadowhuntress. But then he thought of Cadair Idris and remembered nearly getting himself killed multiple times because he had been too distracted following the dark haired girl's every movement and thinking that in that moment she resembled a living flame and that if he had dared to touch her, he'd have been burnt.

"Gabriel!" Only then did the green eyed boy realize that Cecily had been calling out for him for a while now. They were standing just outside the Tower's door.

"Yes?"

"The door is locked." She seemed almost annoyed, as though she'd told him that before.

Gabriel smiled at the fact that a simple door could stop the Herondale girl.

"Never heard of a rune, Cecy?" As he spoke he took his stele out of his pocket.

The girl's eyes narrowed as though she was trying to figure out whether the Lightwood was making fun of her or simply giving her a tip. A moment later, she shrugged.

"Are you saying that I should use a strength rune to make the door collide?" Cecily took Gabriel's stele away from him as she spoke, ready to put her idea at work. "And it's Miss Herondale to you."

The green eyed boy couldn't help but to laugh this time.

"Well, Miss Herondale, I don't think that would be the wisest choice," he said, recovering his stele with a fast movement of his hand. "Despite being quite blind, I do think mundanes would notice a broken door. I do admire your dramatic thinking though."

The boy was still smiling, what made Cecy wonder why the hell he didn't do it very often before the met.

"What do you suggest then?" She was getting impatient. Gabriel couldn't be more amused.

The Lightwood boy placed his stele on the wooden door and slowly, but precisely – as though to irritate the blue eyed girl even more – drew a run. When he was done, the young Shadowhuntress could translate the rune to 'Open'.

"Unlocks anything," Gabriel said, opening the door as if to prove himself true. Together, the stepped into the cold darkness.

After a few steps, the Lightwood grasped the girl's wrist, warning her to stop.

"Huh." He said.

"What?" Cecily whispered, searching the dimness for any threat; hand in weapon.

"It's all too qui-" But the brown haired boy never got to finish his sentence, as a Shadowhunter knife nearly blinded him. Luckily, he caught it mid-air, getting his hand cut – nothing that he couldn't heal with an Iratze. "What the hell?"

A skinny silhouette appeared in front of them from up, as though it had jumped from a superior floor.

The couple and the figure stared at each other for a second, but then the party joiner spoke.

"You shall excuse my throw, but I thought I'd smelled demon blood. My mistake, Mr Lightworm."

"Will," Cecy intervened on Gabriel's behalf. "What are you doing here? You said you were going to stay in the Institute."

"Actually, dear sister, I said that I was going to my bedroom, I made no commentary on the matter of staying there." Cecily rolled his eyes to him. "At any rate," Will continued, "I shall not be the one to interrupt your carefully planned, hmm, should I call it a date?"

Cecily looked at her inviter, not knowing what to say.

"Demon slaying party," Gabriel answered, his whole good mood having drained out of his body like the blood that was draining from his hand.

"Sorry to hear that then, seeing that I've slayed every demon I could find in this place. In fact, I've slayed every demon I could find in the entire London City," Will said, as if he was actually annoyed with the fact. "But the roof view is great."

The Lightwood boy and the Herondale girl stared at each other, speechless.

"At any rate, if any harm comes to my little sister, I'll have to turn this to a Lightworm slaying party. Have fun!"

And with no further words, the dark haired boy took his knife from Gabriel's hands and left the couple alone, whistling as he walked.

Once the whistling was no longer audible, the young Shadowhunter and the blue eyed girl both spoke at the same time.

She: "His he nuts?"

Him: "Why couldn't he be the sick one?"

"Mr Lightwood!" Cecy couldn't believe what she'd just heard. She knew that Gabriel and Will had never gotten along, but wishing upon each other's death…

"I'm sorry, I know he is your brother, but having him turned into a Silent Brother would make our lives much easier."

The girl knew he was right, yet she loved Will, so she had to stand up for him.

"He's just going through a bad phase. This whole Jem thing is still too fresh in his mind."

"Alright," he said, ending the conversation. "Let's just climb the roof, shall we. We're here after all."

Cecily smiled and after she insisted on drawing an Iratze on Gabriel's hand and he allowed her to, they started climbing the stairs that led to the roof.

They were almost there when a Lism, a flying demon, unexpectedly came in through the window the Lightwood was passing by and threw him out the stairs into the void. His body smashing the wooden handrail as he hit it.

"GABRIEL!" The dark haired girl was screaming for her loved one, as she tilted over the handrail.

After a few seconds of panic, an answer came.

"How come you get to call me by first terms and I have to call you Miss Herondale?"

Cecy followed his voice and found him holding on to a torch hanger and trying to pull himself up. The demon was flying in circles around him, occasionally using its horns to make the boy swing unsteadily.

Using one of the throwing techniques the emerald eyed boy had taught her, Cecily threw her knife at the demon, allowing Gabriel to climb back to the stair row. The Herondale ran to meet him.

"Are you okay?"

"Yes," the Shadowhunter had his blade in hand already, despite having said hand still bleeding. "Let's just get the damn thing and send it back to its devilish confines."

Together, they ran around the stairs, trying to conceal the minor demon in a corner. When they finally managed to slay it, Gabriel was outside the door that led to the roof and Cecily was chasing the Lism, leading him that way. Before their eyes, the demon turned into ashes, as Gabriel's Seraph blade, which he'd called Tennin, trespassed the place where the demon's heart should have been.

Exhausted from the run, the two Shadowhunters fell to their butts, side by side, and right below the enormous clock.

The Lightwood boy glanced at his breathless lover girl, and just as he noticed how the moonlight made the blue of her eyes brighter, he finally understood why had part of his brain told him that it was okay to bring the dark haired girl out chasing demons – no matter how unexperienced she was, she had been born a Shadowhuntress from head to toe, and a naturally talented one, he could tell.

Cecy felt him staring and looked back at him; the wind making her hair dangle around her neck. In the heat of the moment, the small girl felt brave enough to peck him softly in the lips.

"Seven," she stated, breaking the silence.

"What?" The Lightwood boy asked, still feeling the dizziness effects of her kiss.

"Our date," she explained. "I had expected maybe a walk by the Thames and perhaps a picnic after for our first date, but who wouldn't prefer to slay a demon? Plus –" The girl made a pause to kiss Gabriel properly this time, "you kissing skills have certainly improved."

"Are you going to rate everything from now on?" The tall boy tried to sound annoyed, but he was more than satisfied with his seven.

Cecy's eyes shone brighter as she gave him a mysterious look.

"Guess you'll have to stick around and find that out by yourself," She said, provocatively.

The Shadowhunter boy laughed and took her in his arms, delightfully feeling her slim delicate body against his skinny one.

It turned out Gabriel had stocked some food there earlier that day, which he had carefully hid on a secret compartment inside the clock machine, so it seemed that Cecily ended up by having her picnic under the moonlight. However had Gabriel romantically planned it or had he simple stored the food because he was constantly hungry? Cecy would never know.

PS. Yes, I realize it sucks. But hey, writing XIX century stories it's not really my area of expertise.
Best, Is (:
